Hi, appologies for writing in English but my German knowledge is utterly basic (ja/nein/retchts/links…)

I love the above extension and it works great in the past years. However, recently I've noticed that it doesn't detect correctly HTML part if the message has Content-Type: multipart/signed; instead of usual Content-Type: multipart/alternative;

Would it be possible to handle HTML messages that are also signed? Thunderbird can display them just fine if forced in the settings.

Hi, thank you for your feedback!

I'll have a look into it. At the moment the addon looks for "text/html" in the message body. Would it be possible to forward a few comparable example messages to me? I need the whole message source code, to have a look into it.

Regards

Hi,

I believe that I have found and fixed it completely for S/MIME encrypted messages.

Unfortunately it's not possible to parse encrypted PGP/MIME messages for the existence of HTML parts. In case of PGP/MIME encrypted messages the addon will now activated the button regardless of the existence of an HTML part.

The fixed version is attached in this post for download:

Updates zu "Allow HTML Temp" und "Abrufen-/Senden-Schaltfläche" für Thunderbird 57+

Unfortunately I wasn't able to prepare complete case messages (will try to manage that shortly) however problematic mail has following sections:

What's more - those are not *encrypted*, only *signed* messages.

I've tried the new version and it seems to be working ok -- even signed messages are detected correctly. Thanks!
